PREPARATION OF ARTIFICIAL SKINS -WITH NATURAL HAIR Filed Oct. 25. 1930 Patented Feb. 2, 1932 DANIEL HAVILAND, onL saw'rELLn, CALIFORNIA 1 PREPARATION or ARTIFICIAL skins WITH NATURAL HAIR f Application linea october 23,1930. 'serial 10.490,721. Y y y.

My invention relates to the preparation of i* to the fur, thev ice having beenremoved; and Fig. V5 shows an enlarged, vertical, detail lartificial skins with natural hair.

Skins with the natural fur thereon are often of little or no value for use in the mak- Ing of fur pieces lor clothing for the reason'v that while the natural hair may be in good condition the skin itself is either so-Vfragile` skin will be used to designate the ynatural lskin with the furxthere'on and the term skin for the skin proper without the fun Y or defective by reason of age or other causes, that their use would be `uneconomic because the skin would soon become torn or disintegrated. i

It is an a 'method whereby the old or defective skin may be removed in a simple and ,efficientl manner and a substitute skin may be firmly" attached to the roots of the fur. The substi- Y' tute skin may be vulcanized to the roots of the fur and also rendered water proof, making it especially adapted for thelining of coats'and the like.

In particular, my invention 'contemplates' freezing the skin with the fur in a block of ice, removing the skinfrom the fur, preparing the roots of the fur to attach a substitute skin, removing the ice, and permanently attaching the substitute skin to the fur. l

l/Vith the above and other objects in view which will appear as the description pro-V ceeds, my invention consists in the steps of the method hereinafter described and claimed. n Y

In the accompanying drawings which form 1 a part of thisspeciication have illustrated diagrammatically the successive steps of the method, and in which: y n' Fig. l is a longitudinal, vertical section showing the fur skin frozen solid Ainv a block of ice;

Fig. 2 is a similar section showing the skin removed with the fur embedded in the ice and the layer of ice adjacent ,the roots of the fur removed therefrom; Y Y Y `Figure 3 shows the next step of temporarily attaching al substitute skin tothe fur r while the latter isstillembedded in the'ice;

To facilitate the description the term fur rhe fur skin l consisting ofthe skin 2 and the fur portion 3 is preferably subjected vto a shrinking Vprocess so as to decrease the area-of the skin and thus compact the furA yThe fur.'skin1 isrplaced into aV suitable container 4 containing water W and is agitated and kneaded so astoiexpel any air occluded in the furB. The water i'spreferablyheated to remove any` dissolved `air and the fur skin .l isdi'sposed horizontally therein by a suitable fastening 5 or'a Vwooden screen or the like@ .The body of Water with the' fur skin ation, turning the same into a'solid block of Vlcegwith the 4furskin l embedded therein.

The block Yof ice'is preferably taken from the Vcontainer 4f and the skin -2 is shaved oif yor removed by a suitable means from the .fur 3.k The topmost layer`V of iceis melted orother -wise removed so asto :efrnposethe roots Bofthe hairfor -a small distance and the same are treated withasuitable'solution to causev .an adhesion between them and the substitute {skln'pto'be applied. 'If a rubberized fabric is l to be used as aV substitute skin :adilu'tesolution of rubber inga suitable volatile solvent' is brushed over the roots .3 of the fur and fabric.

bonding between the fur and the rubberized Y z v Y so rThe ltherein is now subjected to a freezing operi V l then a substitute skin such as a rubberized If the new fur skin is to be used as a lining for fur coats and the like the rubberized fabric 6 may be provided with an outer water proof layer 7, preferably made of rubber.

My method contemplates the use of a. large number of small pieces of fur skins which may be matched and assembled and temporarily fastened as by stitching or the like t a thin fabric so that a new fur skin of any lf, desired size may be made.

In place of a. rubberized fabric any other fabric or a suitable sheet such as flexible leather and the like may be used, and any other attaching means in place of the rubber solution may be employed. It may not always be necessary to expose the roots of the fur for a slight distance and give them a preliminary treatment for attachment to the substitute skin but the preliminary treatment of the roots of the fur by removing' the layer of ice adjacent thereto is preferred.

Various changes may be made in the steps of the method by these skilled in the art Without departing from the spirit of my invention as claimed.

I claim:

l. A method of preparing an artificial skin for fur skins comprising shrinking the fur skin to compact'the fur thereon, immers ing the same in water and removing occluded air from the fur and dissolved air from the water, arranging the fur skin in a horizontal position, freezing the water that the fur skin will be embedded in the ice formed, cutting away the skin while leaving the fur embedded in the ice, exposing the roots of the fur for a slight distance by removing the ice therefrom, applyinga Arubber solution there to, attaching a rubberized fabric to the roots of the fur, removing the ice from the fur,

and vulcanizing the fabric to the fur.

2. A method of preparing` an artificial skin for fur skins comprising immersing the fur skin in water and removing and expelling the air from the fur and from the Water. freezing the water to embed the fur skin in a solid block of ice, removing the skin while leaving the fur embedded in the ice, exposing the roots of the fur for a slight distance and applying a rubber solution thereto, attaching a rubberized fabric to the roots of the fur, removing the ice from the fur and vulcanizing the fabrie'to the fur.

In testimony whereof I have signed my name to this specification.
